I make the Quickie and Fix panels in my garage, with a drill press...
They are cut by hand on a table saw, and they get a pass or two on an edge router to clean off the saw cut marks on the edges.
All of this is done by hand, so the Quickie plates can have some variations. I'd say 10"x6", +/- 1/16". Typically, I try to get them just a hair on the small side.
